The evolutionary basis for ticklish armpits.

This evening I set to work studying, amongst other things, the anatomy of the axilla. I.e. the armpit. As it turns out, the armpit has function apart from repelling treadmill neighbors at the gym: it houses many important structures, including the axillary artery and brachial plexus–a branch of nerves that give function to the entire arm. 89 more words

Buffered Qualitative Stability explains the robustness and evolvability of transcriptional networks

The gene regulatory network (GRN) is the central decision‐making module of the cell. We have developed a theory called Buffered Qualitative Stability (BQS) based on the hypothesis that GRNs are organised so that they remain robust in the face of unpredictable environmental and evolutionary changes. 110 more words
